On my '70, the second switch is a map light. FWIW, I've never seen a
wiring diagram that accurately reflects the wiring of my car -- which
I'm pretty sure is original, or at least was original until I started
adding relays etc.
A few years ago I got a burst of enthusiasm and started pasting
things together to make a diagram of my car... If I can find that,
I'll let you know what that says about the map light wiring.
